Very early research

The research is at the earliest stage – mostly cells in a lab dish. It is far too early to say much.

Also called Thymus extract peptide / Timalin

A thymus gland extract used in Russia. Very little research outside Russian journals.

In animal studies

These are doses given to animals, usually per kilogram of body weight. They do not convert directly to a human dose.

    “A comparative study of polypeptides extracted from the tissues of calves: Cortexin (from brain cortex), Epinorm (from pineal gland), Ventvil (from liver), Prostatilen (from prostate), Thymalin (from thymus), Chelohart (from heart), Chondrolux (from cartilage) on the relevant organotypic tissue cultures of young and old rats, in concentration 0,01-100 ng/ml was performed.”
